4. With a variety of process pipelines, convenient for users to choose;
5. The cold end detects the ambient temperature for temperature compensation, so as to avoid the influence of ambient temperature change on the furnace temperature and avoid interlayer interference;
6. Multiple groups of PID parameters can be stored for system operation call function, with multi-point temperature compensation
7. Gas flow adopts digital precision control, adopts analog signal closed-loop control, strong and weak electricity are separated, and all kinds of data interaction adopts standard bus to improve anti-interference ability and ensure data safety; Gas opening has the function of slow start;
8. With a variety of alarm functions and safety protection functions;
9. Automatic adjustment of constant temperature zone, cascade control, can accurately control the actual process temperature of the reaction tube;
10. The pressure automatic adjustment technology introduces the pressure parameter into the crystal silicon oxidation process, effectively reducing the interference of the tail exhaust on the process and reducing the process fluctuation caused by the exhaust air.
